Certain capitalized terms used herein are defined in Section 7.1.

WHEREAS, on March 12, 2008, the Securityholders party thereto entered into the initial Securityholders Agreement of PG Holdco, LLC (the “Original Agreement”);

WHEREAS, on March 9, 2010, the Original Agreement was amended and restated (the “Amended and Restated Securityholders Agreement”), in accordance with the terms of the Original Agreement, to reflect certain modifications set forth therein; and

WHEREAS, the Management Committee, the Company and the Vestar Majority Holders desire to amend and restate the Amended and Restated Securityholders Agreement, in accordance with the terms of the Amended and Restated Securityholders Agreement, to reflect the terms set forth herein.

NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein, the parties hereto, each intending to be legally bound, agree as follows:

(b) this Agreement has been duly and validly executed and delivered by the Company and constitutes a legal and binding obligation of the Company, enforceable against the Company in accordance with its terms; and

(c) the execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated hereby will not, with or without the giving of notice or lapse of time, or both (i) violate any provision of law, statute, rule or regulation to which the Company is subject, (ii) violate any order, judgment or decree applicable to the Company, or (iii) conflict with, or result in a breach or default under, any term or condition of the Company’s organizational documents or any agreement or instrument to which the Company is a party or by which it is bound.

1.2 Representations and Warranties of the Securityholders. Each Securityholder (as to himself or itself only) represents and warrants to the Company and the other Securityholders that, as of the time such Securityholder becomes a party to this Agreement:

(a) this Agreement (or the separate joinder agreement executed by such Securityholder) has been duly and validly executed and delivered by such Securityholder, and this Agreement constitutes a legal and binding obligation of such Securityholder, enforceable against such Securityholder in accordance with its terms; and

(b) the execution, delivery and performance by such Securityholder of this Agreement (or any joinder to this Agreement) and the consummation by such Securityholder of the transactions contemplated hereby (and thereby) will not, with or without the giving of notice or lapse of time, or both, (i) violate any provision of law, statute, rule or regulation to which such Securityholder is subject, (ii) violate any order, judgment or decree applicable to such Securityholder, or (iii) conflict with, or result in a breach or default under, any term or condition of any agreement or other instrument to which such Securityholder is a party or by which such Securityholder is bound.

ARTICLE II

VOTING AGREEMENTS

2.1 Election of Management Committee Members and Directors. (a) Each Person, other than the Company, that is a party to this Agreement hereby agrees that such Person will vote, or cause to be voted, all voting securities of the Company over which such Person has the power to vote or direct the voting, and will take all other necessary or desirable action within such Person’s control, and the Company will take all necessary and desirable actions within its control, to cause the authorized number of members or directors for each of the respective management committee or board of directors of the Company and PGA Holdings to be established at up to nine members/directors, and to elect or cause to be elected to the respective management committee or board of directors of PGA Holdings and cause to be continued in office, the following individuals:

(i) up to eight members/directors designated by the Vestar Majority Holders (the “Vestar Directors”); and

(ii) one member/director who shall be the Chief Executive Officer of PGA

Holdings (the “Management Director”).

(b) If at any time the Vestar Majority Holders shall notify the other parties to this Agreement of their desire to remove, with or without cause, any individual from a Company or Subsidiary directorship for which such Person or Persons have designation rights pursuant to paragraph (a) above, all such parties so notified will vote, or cause to be voted, or execute a written consent with respect to, all voting securities of the Company and the aforementioned Subsidiaries over which they have the power to vote or direct the voting, and shall take all such other actions promptly as shall be necessary or desirable to cause the removal of such director.

(c) If at any time any Management Director or Vestar Director ceases to serve on the management committee or board of directors of the Company or PGA Holdings (whether due to resignation, removal or otherwise), the Vestar Majority Holders shall be entitled to designate a successor member/director to fill the vacancy created thereby. Each Person that is a party hereto agrees to vote, or cause to be voted, or execute a written consent with respect to, all voting securities of the Company and the aforementioned Subsidiaries over which such Person has the power to vote or direct the voting, and shall take all such other actions as shall be necessary or desirable to cause the designated successor to be elected to fill such vacancy.

(d) Nothing in this Agreement shall be construed to impair any rights that the unitholders or stockholders of the Company or any Subsidiary of the Company may have to remove any director for cause under applicable law, the LLC Agreement or the organizational documents of the Company or such Subsidiary, as the case may be. No such removal of an individual designated pursuant to this Section 2.1 for cause shall affect any of the Securityholders’ rights to designate a different individual pursuant to this Section 2.1 to fill the position from which such individual was removed.

(e) The provisions of this Section 2.1 shall remain in effect following a Public Offering.

2.2 Other Voting Matters. (a) Subject to Section 7.5 of the LLC Agreement, each party to this Agreement hereby agrees that such party will vote, or cause to be voted, all voting securities of the Company and its Subsidiaries over which such party has the power to vote or direct the voting, either in person or by proxy, whether at a securityholders meeting, or by written consent, in the manner in which Vestar directs in connection with the approval of any amendment or amendments to the Company’s organizational documents, the merger, security exchange, combination or consolidation of the Company with any other Person or Persons, the sale, lease or exchange of all or substantially all of the property and assets of the Company and its Subsidiaries on a consolidated basis, and the reorganization, recapitalization, liquidation, dissolution or winding-up of the Company.

(b) In order to effectuate the provisions of Sections 2.1 and 2.2 hereof, each holder of Employee Securities hereby grants to the Chief Executive Officer of the Company, or if the Chief Executive Officer of the Company shall be unable to exercise this proxy due to illness or absence or if the position of Chief Executive Officer of the Company shall be vacant, to the Chief Financial Officer of the Company, a proxy to vote at any annual or special meeting of Securityholders, or to take any action by written consent in lieu of such meeting with respect

to, or to otherwise take action in respect of, all of the Securities owned or held of record by such holder in connection with the matters set forth in Sections 2.1 and 2.2 hereof in accordance with the provisions of Sections 2.1 and 2.2 hereof. Each of the proxies granted hereby is irrevocable and is coupled with an interest. To effectuate the provisions of this Article II, the Secretary of each of the Company and each of the aforementioned Subsidiaries of the Company, or if there be no Secretary such other officer or employee of the Company or such Subsidiaries as the management committee or board of directors (or similar governing body) of the Company or such Subsidiaries may appoint to fulfill the duties of the Secretary, shall not record any vote or consent or other action contrary to the terms of this Article II.

ARTICLE III

TRANSFERS OF SECURITIES

3.1 Restrictions on Transfer of Employee Securities and Co-Investor Securities. (a) Prior to the earlier of (i) a Sale of the Company and (ii) the fifth anniversary of the Closing Date, no holder of Employee Securities may Transfer any Employee Securities, except in an Exempt Employee Transfer.

(b) Without the prior written consent of Vestar, prior to a Sale of the Company, no holder of Co-Investor Securities may Transfer any Co-Investor Securities, except (i) to an Affiliate which is a Controlled Affiliate of the ultimate Controlling Person of such Co-Investor, (ii) pursuant to an exercise of tag-along rights as an Other Holder under Section 3.3, (iii) pursuant to a Sale of the Company under Section 4.1 or other transaction approved under Section 2.2, (iv) pursuant to an exercise of incidental registration rights pursuant to Section 5.2, (v) incidental to the exercise, conversion or exchange of such securities in accordance with their terms, any combination of shares (including any reverse stock split), (vi) as a pledge to financing sources of the Co-Investor, or (vi) to Vestar in connection with any recapitalization, reorganization or reclassification of, or any merger or consolidation involving, the Company; provided, that if Vestar Transfers Securities in a Rule 144 Sale and does not afford a Co-Investor the opportunity to participate in such Transfer on a pro rata basis on the same terms, then such Co-Investor may Transfer in a Rule 144 Sale a number of Securities of the same type and class as the Securities so transferred by Vestar constituting the same percentage of its total holdings of such type and class of Securities as the aforementioned Securities Transferred by Vestar constituted of Vestar’s total holdings.

3.2 Right of First Refusal. (a) If, at any time on or after the fifth anniversary of the Closing Date and prior to the earlier of (i) a Public Offering resulting in a public market for the Securities and (ii) a Sale of the Company, any holder of Employee Securities (for purposes of this Section 3.2(a), a “Selling Employee Holder”) proposes to sell any or all of his Employee Securities (other than a Transfer described in Section 3.3(b)) to a third party (a “Proposed Sale”), such Selling Employee Holder shall first notify the Company in writing, which notice shall (x) state such Selling Employee Holder’s intention to sell Employee Securities to one or more persons, the amount of Employee Securities to be sold, the purchase price therefor, the identity of each prospective transferee, if known, and the other material terms of the Proposed Sale and (y) contain an irrevocable offer to sell such Employee Securities to the Company (in the manner set forth below) at a purchase price equal to the price contained in, and

on the same terms and conditions of, the Proposed Sale (such notice, the “Proposed Sale Notice”).

(b) At any time within thirty (30) days after the date of the receipt by the Company of the Proposed Sale Notice, the Company shall have the right and option to purchase, or to arrange for a third party to purchase, all of the Employee Securities covered by the Proposed Sale Notice at the same price and on the same terms and conditions of the Proposed Sale (or, if the Proposed Sale includes any consideration other than cash, then, at the sole option of the Company, at the equivalent all cash price, determined in good faith by the management committee or board directors of the Company, as applicable), by delivering a certified bank check or checks in the appropriate amount (or by wire transfer of immediately available funds, if the Selling Employee Holder provides to the Company wire transfer instructions) (and any such non-cash consideration to be paid) to the Selling Employee Holder at the principal office of the Company or one of its Subsidiaries against delivery of certificates or other instruments representing the Employee Securities so purchased, appropriately endorsed by the Selling Employee Holder. If at the end of the 30-day period, the Company or such third party has not tendered the purchase price for such Employee Securities in the manner set forth above, the Selling Employee Holder may, during the succeeding 30-day period, sell not less than all of the Employee Securities covered by the Proposed Sale to a third party on terms no less favorable to Selling Employee Holder than those contained in the Proposed Sale Notice. Promptly after such sale, the Selling Employee Holder shall notify the Company of the consummation thereof and shall furnish such evidence of the completion and time of completion of such sale and of the terms thereof as may reasonably be requested by the Company. If, at the end of thirty (30) days following the expiration of the 30-day period during which the Company is entitled hereunder to purchase the Employee Securities, the Selling Employee Holder has not completed the sale of such Employee Securities as aforesaid, all of the restrictions on sale, transfer or assignment contained in this Agreement shall again be in effect with respect to such Employee Securities.

3.3 Restrictions on Transfers of Vestar Securities.

(a) Tag-Along Rights. Subject to the next paragraph, prior to making any Transfer of Vestar Securities (other than a Transfer described in Section 3.3(b)) any holder of Vestar Securities proposing to make such a Transfer (for purposes of this Section 3.3, a “Selling Vestar Holder”) shall give at least fifteen (15) days’ prior written notice to each holder of Employee Securities and each holder of Co-Investor Securities (for purposes of this Section 3.3, each an “Other Holder”), and the Company, which notice (for purposes of this Section 3.3, the “Sale Notice”) shall identify the type and amount of Vestar Securities to be sold (for purposes of this Section 3.3, the “Offered Securities”), describe the terms and conditions of such proposed Transfer, and identify each prospective transferee. Any of the Other Holders may, within ten (10) days of the receipt of the Sale Notice, give written notice (each, a “Tag-Along Notice”) to the Selling Vestar Holder that such Other Holder wishes to participate in such proposed Transfer upon the terms and conditions set forth in the Sale Notice, which Tag-Along Notice shall specify the Securities such Other Holder desires to include in such proposed Transfer; provided, however, that (1) each Other Holder shall be required, as a condition to being permitted to sell Securities pursuant to this Section 3.3(a) in connection with a Transfer of Offered Securities, to elect to sell Securities of the same type and class, only to the extent such Securities are vested (or may become vested as a result of such Transfer) pursuant to the terms and conditions set forth in

the applicable Management Unit Subscription Agreement, and in the same relative proportions (which proportions shall be determined on a Unit for Unit or, as the case may be, share for share basis and on the basis of aggregate liquidation value with respect to Preferred Units or Preferred Stock) as the Securities which comprise the Offered Securities, and (2) to exercise its tag-along rights hereunder, each Other Holder must agree to make to the transferee the same representations, warranties, covenants, indemnities and agreements as the Selling Vestar Holder agrees to make in connection with the Transfer of the Offered Securities (except that in the case of representations and warranties pertaining specifically to, or covenants made specifically by, the Selling Vestar Holder, the Other Holders shall make comparable representations and warranties pertaining specifically to (and, as applicable, covenants by) themselves), and must agree to bear his or its ratable share (for which they shall be severally liable based on the value of Securities that are Transferred; provided that such liability of any Other Holder shall not exceed the gross proceeds received by such Other Holder in the Transfer) of all liabilities to the transferees arising out of representations, warranties and covenants (other than those representations, warranties, covenants and indemnitees that pertain specifically to a given Securityholder, who shall bear all of the liability related thereto), indemnities or other agreements made in connection with the Transfer; provided, that no Securityholder shall be required to make representations or warranties that pertain specifically to the Company or its Subsidiaries (although each Securityholder must nevertheless bear its ratable share of any indemnification liability for any breach of any such representation or warranty) or, in the case of holders of Co-Investor Securities only, agree to any non-competition covenants or agreements. Each Securityholder will bear (x) its or his own costs of any sale of Securities pursuant to this Section 3.3(a) and (y) its or his pro-rata share (based upon the relative amount of Securities sold) of the costs of any sale of Securities pursuant to this Section 3.3(a) (excluding all amounts paid to any Securityholder or his or its Affiliates as a transaction fee, broker’s fee, finder’s fee, advisory fee, success fee, or other similar fee or charge related to the consummation of such sale) to the extent such costs are incurred for the benefit of all Securityholders and are not otherwise paid by the transferee.

If none of the Other Holders gives the Selling Vestar Holder a timely Tag-Along Notice with respect to the Transfer proposed in the Sale Notice, then (notwithstanding the first sentence of this Section 3.3(a)) the Selling Vestar Holder may Transfer such Offered Securities on the terms and conditions set forth, and to or among any of the transferees identified (or Affiliates of transferees identified), in the Sale Notice at any time within ninety (90) days after expiration of the ten-day period for giving Tag-Along Notices with respect to such Transfer. Any such Offered Securities not Transferred by the Selling Vestar Holder during such 90-day period will again be subject to the provisions of this Section 3.3(a) upon subsequent Transfer. If one or more Other Holders give the Selling Vestar Holder a timely Tag-Along Notice, then the Selling Vestar Holder shall use all reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of the Other Holders in any contemplated Transfer, on the same terms and conditions as are applicable to the Offered Securities, and no Selling Vestar Holder shall transfer any of its units or shares, as the case may be, to any prospective transferee if such prospective transferee(s) declines to allow the participation of the Other Holders, unless the Selling Vestar Holder agrees to purchase the Units that such Other Holders are entitled to sell and have elected to sell in connection with such Transfer. If the prospective transferee(s) is unwilling or unable to acquire all of the Offered Securities and all of the Securities specified in a timely Tag-Along Notice upon such terms, then the Selling Vestar Holder may elect either to

cancel such proposed Transfer or to allocate the maximum number of each class of Securities that the prospective transferees are willing to purchase (the “Allocable Shares”) among the Selling Vestar Holder and the Other Holders giving timely Tag-Along Notices as follows (it being understood that the prospective transferees shall be required to purchase Securities of the same class, only to the extent such Securities are vested (or may become vested as a result of such Transfer) pursuant to the terms and conditions set forth in the applicable Management Unit Subscription Agreement, on the same terms and conditions taking into account the provisions of clause (1) of the first paragraph of this Section 3.3(a), whether or not they are represented by voting trust certificates, and to consummate such Transfer on those terms and conditions):

(i) each participating Securityholder (including the Selling Vestar Holder) shall be entitled to sell a number of Units or shares of each class of Securities (taking into account the provisions of clause (1) of the first paragraph of this Section 3.3(a)) (not to exceed, for any Other Holder, the number of Units or shares of such class of Securities identified in such Other Holder’s Tag-Along Notice) equal to the product of (A) the number of Allocable Shares of such class of Securities and (B) a fraction, the numerator of which is such Securityholder’s Ownership Percentage of such class of vested Securities and the denominator of which is the aggregate Ownership Percentage for all participating Securityholders of such class of Securities; provided, however, that if a Securityholder was unable to sell Securities in one or more prior Transfers effected pursuant to this Section 3.3(a) because of clause (2) of the first paragraph of this Section 3.3(a) and, as a result, the aggregate percentage of Securities sold by such Securityholder in Transfers effected pursuant to this Section 3.3(a) is less than the aggregate percentage of Securities sold by Vestar in such Transfers, then additional Allocable Shares shall be allocated to such Securityholder (not to exceed the number of Securities identified in such Securityholder’s Tag-Along Notice) in priority over other Securityholders until, after giving effect to the Transfer proposed to be effected, the aggregate percentage of Securities sold by Vestar and such Securityholder are equal; and

(ii) if after allocating the Allocable Shares of any class of Securities to such Securityholders in accordance with clause (i) above, there are any Allocable Shares of such class that remain unallocated, then they shall be allocated (in one or more successive allocations on the basis of the allocation method specified in clause (i) above) among the Selling Vestar Holder and each such Other Holder that has elected in its Tag-Along Notice to sell a greater number of Units or shares of such class of Securities than previously has been allocated to it pursuant to clause (i) and this clause (ii) (all of whom (but no others) shall, for purposes of clause (i) above, be deemed to be the participating Securityholders) until all such Allocable Shares have been allocated in accordance with this clause (ii).

(b) Excluded Transfers. The rights and restrictions contained in Section 3.3(a) shall not apply with respect to any of the following Transfers of Securities:

(i) any Transfer of Vestar Securities in a Public Sale;

(ii) any Transfer of Vestar Securities to and among (A) the members or partners of Vestar and the members, partners, securityholders and employees of such

partners or (B) wholly owned subsidiaries of Vestar or any Person controlled by or under the common control with Vestar and its affiliated funds (but excluding any portfolio company of Vestar or its affiliated funds) or (C) any Person controlled by any Person described above (subject to compliance with Sections 3.4 and 3.5 hereof);

(iii) any Transfer of Vestar Securities in accordance with Section 4.1;

(iv) any Transfer of Vestar Securities incidental to the exercise, conversion or exchange of such securities in accordance with their terms or any reclassification or combination of shares (including any reverse stock split);

(v) any Transfer of Vestar Securities to employees or directors of, or consultants to, any of the Company and its Subsidiaries; and

(vi) any Transfer constituting an Exempt Individual Transfer.

(c) Excluded Securities. No Securities that have been transferred by the Selling Vestar Holder or an Other Holder in a Transfer pursuant to the provisions of Section 3.3(a) (“Excluded Securities”) shall be subject again to the restrictions set forth in Section 3.3(a), nor shall any Securityholder holding Excluded Securities be entitled to exercise any rights as an Other Holder under Section 3.3(a) with respect to such Excluded Securities, and no Excluded Securities held by a Selling Vestar Holder or any Other Holder shall be counted in determining the respective participation rights of such Holders in a Transfer subject to Section 3.3(a).

(d) The provisions of this Section 3.3 shall remain in effect following a Public Offering.

3.4 Transfer to Company Competitor. Notwithstanding the foregoing, unless Vestar agrees in writing to the contrary, no Employee or Co-Investor (or transferee thereof) shall Transfer any of its Securities at any time to a Company Competitor or a Person that has been deemed by the management committee or board of directors of the Company or PGA Holdings to be materially adverse to the Company; provided that following a Public Offering, such restriction shall not apply to sales in an open market transaction as long as the selling Securityholder has no knowledge that the recipient is a Company Competitor or has been deemed by the management committee or board of directors of the Company or PGA Holdings to be materially adverse to the Company.

3.5 Securities Act Compliance. No Securities may be transferred by a Securityholder (other than pursuant to an effective registration statement under the Securities Act) unless such Securityholder first delivers to the Company an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to the Company, to the effect that such Transfer is not required to be registered under the Securities Act.

3.6 Certain Transferees Bound by Agreement. Subject to compliance with the other provisions of this Article III, any Securityholder may Transfer any Securities held by such Securityholder in accordance with applicable law; provided, however, that if the Transfer is not made pursuant to a Public Sale or a transaction the consummation of which will cause the

termination of this Agreement pursuant to Article VI, then the Transferor of such Security shall first deliver to the Company a written agreement of the proposed transferee (excluding a transferee that is a Limited Partner) to become a Securityholder and to be bound by the terms of this Agreement (unless such proposed transferee is already a Securityholder). All Employee Securities will continue to be Employee Securities in the hands of any transferee (other than the Company, Vestar, a Co-Investor or any transferee in a Public Sale or pursuant to a sale under Section 3.3(a)); provided that Employee Securities Transferred pursuant to an exercise of tag-along rights as an Other Holder under Section 3.3(a) shall not be subject to the provisions of Section 3.1 in the hands of the transferee or any subsequent transferee. All Co-Investor Securities will continue to be Co-Investor Securities in the hands of any transferee (other than the Company, Vestar, the Employees or a transferee in a Public Sale or pursuant to a sale under Section 3.3(a)); provided that Co-Investor Securities Transferred pursuant to an exercise of tag-along rights as an Other Holder under Section 3.3(a) shall not be subject to the provisions of Section 3.1 in the hands of the transferee or any subsequent transferee. All Vestar Securities will continue to be Vestar Securities in the hands of any transferee (other than the Company, the Co-Investors, the Employees or a transferee in a Public Sale).

3.7 Transfers in Violation of Agreement. Any Transfer or attempted Transfer of any Securities in violation of any provision of this Agreement shall be void, and the Company shall not record such Transfer on its books or treat any purported transferee of such Securities as the owner of such Securities for any purpose.

ARTICLE IV

DRAG-ALONG RIGHTS

ON APPROVED SALE

4.1 Drag-Along Rights. (a) Subject to the next paragraph, if Vestar elects to consummate, or to cause the Company to consummate, a transaction constituting a Sale of the Company, Vestar shall notify the Company and the other Securityholders in writing of that election, the other Securityholders will consent to and raise no objections to the proposed transaction, and the Securityholders and the Company will take all other actions reasonably necessary or desirable to cause the consummation of such transaction on the terms proposed by Vestar (a “Drag Along Sale”). Without limiting the foregoing, (i) if the proposed Drag Along Sale is structured as a sale of assets or a merger or consolidation, or otherwise requires stockholder approval, the Securityholders and the Company will vote or cause to be voted all Securities that they hold or with respect to which such Securityholder has the power to direct the voting and which are entitled to vote on such transaction in favor of such transaction and will waive any appraisal rights which they may have in connection therewith, and (ii) if the proposed Drag Along Sale is structured as or involves a sale or redemption of Securities, the Securityholders will agree to sell their pro-rata share of the Securities being sold in such Drag Along Sale on the terms and conditions approved by Vestar, and the Securityholders will execute any merger, asset purchase, security purchase, recapitalization or other sale agreement approved by Vestar in connection with such Sale of the Company, which may require the Securityholders to make to the transferee the same representations, warranties, covenants, indemnities and agreements as Vestar agrees to make in connection with such Sale of the Company (except that in the case of representations and warranties pertaining specifically to, or covenants made specifically by, Vestar, the other Securityholders shall make comparable representations and

warranties pertaining specifically to (and, as applicable, covenants by) themselves), and must agree to bear his or its ratable share (for which they shall be severally liable based on the value of Securities that are Transferred; provided that such liability of any Securityholder shall not exceed the gross proceeds received by such Securityholder in the transaction) of all liabilities to the transferees arising out of representations, warranties and covenants (other than those representations, warranties, covenants and indemnitees that pertain specifically to a given Securityholder, which shall bear all of the liability related thereto), indemnities or other agreements made in connection with the transaction; provided, that no Securityholder shall be required to make representations or warranties that pertain specifically to the Company or its Subsidiaries (although each Securityholder must nevertheless bear its ratable share of any indemnification liability for any breach of any such representation or warranty) or , in the case of holders of Co-Investor Securities only, agree to any non-competition covenants or agreements.

(b) The obligations of the Securityholders with respect to the Drag Along Sale are subject to the satisfaction of the following conditions: (i) upon the consummation of the Drag Along Sale, all of the holders of a particular class or series of Securities (if any consideration is to be received by any of them) shall receive the same form and amount of consideration per share, Unit or amount of Securities, only to the extent such shares, Units or Securities are vested (or may become vested as a result of such Transfer) pursuant to the terms and conditions set forth in the applicable Management Unit Subscription Agreement, or if any holders of a particular class or series of Securities are given an option as to the form and amount of consideration to be received, all holders of such class or series, only to the extent such Securities are vested (or may become vested as a result of such Transfer) pursuant to the terms and conditions set forth in the applicable Management Unit Subscription Agreement, will be given the same option, (ii) if consideration is to be received by holders of Securities, all holders of then currently exercisable rights to acquire a particular class or series of Securities will be given an opportunity to either (A) exercise such rights prior to the consummation of the Drag Along Sale and participate in such sale as holders of such Securities or (B) upon the consummation of the Drag Along Sale, receive in exchange for such rights consideration equal to the amount determined by multiplying (1) the same amount of consideration per share, Unit or amount of Securities received by the holders of such type and class of Securities in connection with the Drag Along Sale less the exercise price per share, Unit or amount of such rights to acquire such Securities by (2) the number of shares, Units or aggregate amount of Securities represented by such rights, and (iii) if consideration is to be received by holders of Securities, the holders of Preferred Units or, as the case may be, Preferred Stock shall receive consideration in respect of all of the issued and outstanding Preferred Units, or, as the case may be, shares of Preferred Stock in such Drag Along Sale having a fair market value equal to the aggregate liquidation value and preferred return of such Preferred Units or, as the case may be, Preferred Stock before any consideration is paid in respect of the Class A Units or, as the case may be, Common Stock in such Drag Along Sale.

(c) Each Securityholder will bear its or his pro-rata share (based upon the relative amount of Securities sold) of the reasonable costs of any sale of Securities pursuant to a Drag Along Sale to the extent such costs are incurred for the benefit of all Securityholders and are not otherwise paid by the Company or the acquiring party. Costs incurred by or on behalf of a Securityholder for its or his sole benefit will not be considered costs of the transaction hereunder. In the event that any transaction that Vestar elects to consummate or cause to be

consummated pursuant to this Section 4.1 is not consummated for any reason, the Company will reimburse Vestar for all actual and reasonable expenses paid or incurred by Vestar in connection therewith.

(d) Notwithstanding any provision in this Agreement to the contrary, but subject to the terms of the Management Agreement, Vestar Capital Partners shall be entitled to be paid customary and reasonable fees by the Company for any investment banking services provided by it in connection with a Sale of the Company.

(e) The provisions of this Section 4.1 shall remain in effect following the first Public Offering.

ARTICLE V

REGISTRATION RIGHTS

5.1 Demand Registrations.

(a) Requests for Registration. Subject to the provisions of this Article V, the holders of a majority of Vestar Securities that constitute Registrable Securities shall have the right (the “Vestar Demand Right”) to request registration under the Securities Act of all or any portion of the Registrable Securities held by such Securityholders (in each case, referred to herein as the “Requesting Holders”) on Form S-1 or any similar long-form registration (“Long-Form Demand Registration”) or on Form S-3 or any similar short-form registration (“Short-Form Demand Registration”), if such registration is available to the Company, by delivering a written notice to the principal business office of the Company, which notice identifies the Requesting Holders and specifies the number of Registrable Securities to be included in such registration (the “Registration Request”). Subject to the restrictions set forth in Section 5.1(d), the Company will give prompt written notice of such Registration Request (the “Registration Notice”) to all other holders of Registrable Securities and will thereupon use its best efforts to effect the registration (a “Demand Registration”) under the Securities Act on any form available to the Company of:

(i) the Registrable Securities requested to be registered by the Requesting Holders;

(ii) all other Registrable Securities of the same type and class which the Company has received a written request to register within 30 days after the Registration Notice is given and any securities of the Company proposed to be included in such registration by the Company for its own account; and

(iii) any securities of the Company proposed to be included in such registration by the holders of registration rights granted other than pursuant to this Agreement (“Other Registration Rights”), provided that the Company has complied with Section 5.1(f) hereof.

(b) Preservation of Demand Registration. A registration undertaken by the Company at the request of the Requesting Holder will not count as a Demand Registration:

(i) if, pursuant to the Vestar Demand Right, the Requesting Holders fail to register and sell at least 75% of the Registrable Securities requested to be included in such registration by them; or

(ii) if the Requesting Holders withdraw a Registration Request (A) upon the determination of the management committee or, as the case may be, the board of directors of the Company to postpone the filing or effectiveness of a Registration Statement pursuant to Section 5.1(d) or (B) within ten (10) days of receiving notice from the Company of its intent to exercise its Priority Right in connection with such registration.

(c) Priority on Demand Registration. If the sole or managing underwriter of a Demand Registration advises the Company in writing that in its opinion the number of Registrable Securities and other securities requested to be included exceeds the number of Registrable Securities and other securities which can be sold in such offering without adversely affecting the distribution of the securities being offered, the price that will be paid in such offering or the marketability thereof, the Company will include in such registration the greatest number of (i) Registrable Securities proposed to be registered by the holders thereof, (ii) securities having Other Registration Rights that are pari passu with the demand rights granted in respect of Registrable Securities hereunder proposed to be registered by the holders thereof and (iii) securities proposed to be registered by the Company for its own account which in the opinion of such underwriters can be sold in such offering without adversely affecting the distribution of the securities being offered, the price that will be paid in such offering or the marketability thereof, ratably among the holders of Registrable Securities, the holders of such Other Registration Rights and the Company, based (A) as between the Company and such holders requesting registration, on the respective amounts of securities requested to be registered, and (B) as among the holders requesting registration, on the respective amounts of Registrable Securities (whether requested to be registered pursuant to Section 5.1 or 5.2) and securities subject to such Other Registration Rights, as the case may be, held by each such holder; provided, however, that the Company shall have the right (the “Priority Right”) to receive priority over all holders of Registrable Securities in any Demand Registration to be effected under this Section 5.1 with respect to securities that the Company proposes to include in such registration for its own account by giving written notice of its election to exercise such Priority Right to the holders of Registrable Securities requesting registration thereof.

(d) Restrictions on Demand Registrations. Except as otherwise provided in this Section 5.1(d), the Company shall be obligated to effect (i) up to three Long-Form Demand Registrations and (ii) unlimited Short-Form Demand Registrations to the extent the Company is a registrant entitled to file a registration statement on Form S-3 or any successor or similar short-form registration statement, in each case pursuant to a Vestar Demand Right. Any Demand Registration requested must be for a firmly underwritten public offering to be managed by an underwriter or underwriters of recognized national standing selected by the Requesting Holders and reasonably acceptable to the Company.

(e) Stock Splits. In connection with any Demand Registration pursuant to this Section 5.1, each party to this Agreement will vote, or cause to be voted, all securities of the Company over which it has the power to vote or direct the voting to effect any stock split which,

in the opinion of the sole or managing underwriter, is necessary to facilitate the effectiveness of such Demand Registration.

(f) Restriction on Other Registration Rights. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any equity securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of at least a majority of the Vestar Securities.

5.2 Incidental Registration.

(a) Requests for Incidental Registration. At any time the Company proposes to register any Securities under the Securities Act (other than registrations on such form(s) solely for registration of Securities in connection with any employee benefit plan or dividend reinvestment plan or a merger or consolidation), including registrations pursuant to Section 5.1(a), whether or not for sale for its own account, the Company will give written notice to each holder of Registrable Securities at least thirty (30) days prior to the initial filing of such Registration Statement with the SEC of its intent to file such registration statement and of such holder’s rights under this Section 5.2. Upon the written request of any holder of Registrable Securities made within twenty (20) days after any such notice is given (which request shall specify the Registrable Securities intended to be disposed of by such holder), the Company will use its best efforts to effect the registration (an “Incidental Registration”) under the Securities Act of all Registrable Securities which the Company, as the case may be, has been so requested to register by the holders thereof; provided, however, that if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the Registration Statement filed in connection with such Incidental Registration (each an “Incidental Registration Statement”), the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to each holder of Registrable Securities and, thereupon, (i) in the case of a determination not to register, the Company shall be relieved of its obligation to register any Registrable Securities under this Section 5.2 in connection with such registration (but not from its obligation to pay the expenses incurred in connection therewith), and (ii) in the case of a determination to delay registration, the Company shall be permitted to delay registering any Registrable Securities under this Section 5.2 during the period that the registration of such other securities is delayed.

(b) Priority on Incidental Registration. If the sole or managing underwriter of a registration advises the Company in writing that in its opinion the number of Registrable Securities and other securities requested to be included exceeds the number of Registrable Securities and other securities which can be sold in such offering without adversely affecting the distribution of the securities being offered, the price that will be paid in such offering or the marketability thereof, the Company will include in such registration the Registrable Securities and other securities of the Company in the following order of priority:

(i) first, the greatest number of Securities of the Company proposed to be included in such registration by the Company for its own account and by holders of Other Registration Rights that have priority over the incidental registration rights granted

to holders of Registrable Securities under this Agreement, which in the opinion of such underwriters can be so sold;

(ii) second, after all Securities that the Company proposes to register for its own account or for the accounts of holders of Other Registration Rights that have priority over the incidental registration rights under this Agreement have been included, the greatest amount of Registrable Securities and securities having Other Registration Rights that are pari passu with Registrable Securities, in each case requested to be registered by the holders thereof which in the opinion of such underwriters can be sold in such offering without adversely affecting the distribution of the securities being offered, the price that will be paid in such offering or the marketability thereof, ratably among the holders of Registrable Securities (whether requested to be registered pursuant to Section 5.1 or 5.2) and securities subject to such Other Registration Rights that are pari passu based on the respective amounts of Registrable Securities and securities subject to such Other Registration Rights held by each such holder; and

(iii) third, any other Securities.

(c) Upon delivering a request under this Section 5.2, a Securityholder (excluding Vestar and its Affiliates, but including any other Permitted Transferee thereof) will, if requested by the Company, execute and deliver a customary custody agreement and power of attorney in form and substance reasonably satisfactory to the Company and one of the Vestar Directors with respect to such Securityholder’s Securities to be registered pursuant to this Section 5.2 (a “Custody Agreement and Power of Attorney”). The Custody Agreement and Power of Attorney will provide, among other things, that the Securityholder will deliver to and deposit in custody with the custodian and attorney-in-fact named therein (who shall be reasonably satisfactory to one of the Vestar Directors) a certificate or certificates representing such Securities (duly endorsed in blank by the registered owner or owners thereof or accompanied by duly executed stock powers in blank) and irrevocably appoint said custodian and attorney-in-fact with full power and authority to act under the Custody Agreement and Power of Attorney on such Securityholder’s behalf with respect to the matters specified therein. Such Securityholder also agrees to execute such other customary agreements as the Company may reasonably request to further evidence the provisions of this Section 5.2.

5.3 Holdback Agreements. (a) Each holder of Registrable Securities agrees that if requested along with all other holders of Registrable Securities in connection with an underwritten offering made pursuant to a Registration Statement for which such Securityholder has registration rights pursuant to this Article V by the managing underwriter or underwriters of such underwritten offering, such holder will not effect any Public Sale or distribution of any of the securities being registered or any securities convertible or exchangeable or exercisable for such securities (except as part of such underwritten offering), during the period beginning ten (10) days prior to, and ending (i) with respect to the initial Public Offering, 180 days after, and (ii) with respect to any underwritten offering subsequent to the initial Public Offering, ninety (90) days after (or, if approved by the Vestar Majority Holders, a longer period up to 180 days after), the closing date of the underwritten offering made pursuant to such Registration Statement (or for such shorter period as to which the managing underwriter or underwriters may agree, provided that such shorter period applies equally to all holders of Registrable Securities).

(b) The Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and during (x) with respect to the initial Public Offering, the 180-day period, and (y) with respect to any underwritten offering subsequent to the initial Public Offering, the 90-day period (or, if approved by the Vestar Majority Holders, a longer period up to 180 days), in each case beginning on the effective date of any underwritten Demand Registration (or for such shorter period as to which the managing underwriter or underwriters may agree), except as part of such Demand Registration or in connection with any employee benefit or similar plan, any dividend reinvestment plan, or a business acquisition or combination and (ii) to use all reasonable efforts to cause each holder of at least 5% (on a fully-diluted basis) of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, which are or may be purchased from the Company at any time after the date of this Agreement (other than in a registered offering) to agree not to effect any sale or distribution of any such securities during such period (except as part of such underwritten offering, if otherwise permitted).

5.4 Registration Procedures. In connection with the registration of any Registrable Securities or a sale of securities pursuant to an effective shelf registration statement, as applicable, the Company shall effect such sales or registrations to permit the sale of such Registrable Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

(a) Prepare and file with the SEC a Registration Statement or Registration Statements on a form available for the sale of the Registrable Securities by the holders thereof in accordance with the intended method of distribution thereof, and use its best efforts to cause each such Registration Statement to become effective;

(b) Prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for a period ending on the earlier of (i) ninety (90) days from the effective date and (ii) such time as all of such securities have been disposed of in accordance with the intended method of disposition thereof; cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and comply with the provisions of the Securities Act, the Exchange Act and the rules and regulations of the SEC promulgated thereunder applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or in such prospectus as so supplemented.

(c) Notify the selling holders of Registrable Securities promptly (but in any event within two business days), and confirm such notice in writing, (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of Registrable Securities the Company becomes aware that the representations and warranties of the Company contained in any agreement (including any underwriting agreement)

contemplated by Section 5.4(h) below cease to be true and correct in all material respects, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Securities for offer or sale in any jurisdiction, or (v) if the Company becomes aware of the happening of any event that makes any statement made in such Registration Statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in such Registration Statement, prospectus or documents so that, in the case of such Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) Use its best efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, and, if any such order is issued, to obtain the withdrawal of any such order at the earliest possible moment.

(e) Deliver to each selling holder of Registrable Securities and the underwriters, if any, without charge, as many copies of the prospectus or prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request; and the Company hereby consents to the use of such prospectus and each amendment or supplement thereto by each of the selling holders of Registrable Securities and the underwriters or agents, if any, in connection with the offering and sale of the Registrable Securities covered by such prospectus and any amendment or supplement thereto.

(f) Prior to any public offering of Registrable Securities, to use its best efforts to register or qualify, and cooperate with the selling holders of Registrable Securities, the underwriters, if any, the sales agents and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or “blue sky” laws of such jurisdictions within the United States as any selling holder or the managing underwriters reasonably request in writing; provided, however, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject.

(g) Upon the occurrence of any event contemplated by Section 5.4(c)(v) above, as promptly as practicable prepare a supplement or post-effective amendment to the Registration Statement or a supplement to the related prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(h) Enter into an underwriting agreement in form, scope and substance as is customary in underwritten offerings and take all such other actions as are reasonably requested by the managing or sole underwriter in order to expedite or facilitate the registration or the disposition of such Registrable Securities, and in such connection, (i) make such representations and warranties to the underwriters, with respect to the business of the Company and its subsidiaries, and the Registration Statement, prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings, and confirm the same if and when requested, (ii) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriters), addressed to the underwriters covering the matters customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by underwriters, (iii) obtain “cold comfort” letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any Subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to each of the underwriters, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings, and (iv) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures no less favorable to the holders of Registrable Securities than those set forth in Section 5.7 hereof (or such other provisions and procedures acceptable to holders of a majority of the Registrable Securities covered by such Registration Statement and the managing underwriters or agents) with respect to all parties to be indemnified pursuant to said Section. The above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder.

(i) Comply with all applicable rules and regulations of the SEC and make generally available to its Securityholders earnings statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than forty-five (45) days after the end of any 12-month period (or ninety (90) days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Company after the effectiveness of a Registration Statement, which statements shall cover said 12-month periods.

(j) (i) Use its best efforts to cause all such Registrable Securities covered by such registration statement to be listed on the principal securities exchange on which Securities are then listed (if any), if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii) if no Securities are then so listed, use its best efforts to, either (as the Company may elect) (x) cause all such Registrable Securities to be listed on a national securities exchange or (y) secure designation of all such Registrable Securities as a NASDAQ “national market system security” within the meaning of Rule 11Aa2-1 or, failing that, to secure NASDAQ authorization for such shares and, without limiting the generality of the foregoing, to arrange for at least two market makers to register as such with respect to such shares with the National Association of Securities Dealers, Inc. (“NASD”).

The Company may require each holder of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding such holder and the distribution of such Registrable Securities as the Company may, from time to time, reasonably request in writing and the Company shall be entitled to rely on such information provided; provided that such information shall be used only in connection with such registration. The Company may exclude from such registration the Registrable Securities of any holder who unreasonably fails to furnish such information promptly after receiving such request. Each holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5.4(c)(ii), 5.4(c)(iv) or 5.4(c)(v), such holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or prospectus until such holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 5.4, or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and has received copies of any amendments or supplements thereto.

5.5 Shelf Registration. Subject to the provisions set forth in Section 5.4, if the holders of a majority of Vestar Securities that constitute Registrable Securities so specify, in the Registration Notice that they desire the Company to undertake a shelf registration of some or all of such Registrable Securities, then the Company shall file with the SEC a registration statement under the Securities Act on the appropriate form pursuant to Rule 415 under the Securities Act (the “Required Registration”). The Company shall use its best efforts to cause the Required Registration to be declared effective under the Securities Act as soon as practical after filing, and once effective, the Company shall cause such Required Registration to remain effective for a period ending on the earliest of (i) the second anniversary of the effectiveness thereof, (ii) the date on which all Registrable Securities have been sold pursuant to the Required Registration and (iii) the date as of which there are no longer any Registrable Securities in existence.

5.6 Registration Expenses. Subject to Section 5.1(b)(i), all fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company, whether or not any Registration Statement is filed or becomes effective, including, without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with the NASD in connection with an underwritten offering and (B) fees and expenses of compliance with state securities or “blue sky” laws), (ii) reasonable messenger, telephone and delivery expenses, (iii) fees and disbursements of counsel for the Company, (iv) fees and disbursements of all independent certified public accountants referred to in Section 5.4(h), (v) underwriters’ fees and expenses (excluding discounts, commissions, or fees of underwriters, selling brokers, dealer managers or similar securities industry professionals relating to the distribution of the Registrable Securities), (vi) Securities Act liability insurance, if the Company so desires such insurance, (vii) internal expenses of the Company, (viii) the expense of any annual audit, (ix) the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and (x) the fees and expenses of any Person, including special experts, retained by the Company. In connection with any Demand Registration or Incidental Registration hereunder, the Company shall reimburse the holders of the Registrable Securities being registered in such registration for the reasonable fees and disbursements of not more than one counsel (together with appropriate local counsel) chosen by the Requesting Holders, if pursuant to a Demand Registration, or the Company, in all other cases, and other reasonable out-of-pocket expenses of

the holders of Registrable Securities incurred in connection with the registration of the Registrable Securities.

5.7 Indemnification; Contribution.

(a) Indemnification by the Company. The Company shall, without limitation as to time, indemnify and hold harmless, to the full extent permitted by law, each holder of Registrable Securities, the officers, directors, agents and employees of each of them, each Person who controls each such holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), the officers, directors, agents and employees of each such controlling person and any financial or investment adviser (each, an “Indemnified Party”), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, actions or proceedings (whether commenced or threatened) reasonable costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and reasonable expenses (including reasonable expenses of investigation) (collectively, “Losses”), as incurred, arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, prospectus or form of prospectus or in any amendment or supplements thereto or in any preliminary prospectus, or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except to the extent that the same arise out of or are based upon information furnished in writing to the Company by such Indemnified Party or the related holder of Registrable Securities expressly for use therein or (ii) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration; provided, however, that the Company shall not be liable to any Person who participates as an underwriter in the offering or sale of Registrable Securities or any other Person, if any, who controls such underwriters within the meaning of the Securities Act to the extent that any such Losses arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus if (x) such Person failed to send or deliver a copy of the prospectus with or prior to the delivery of written confirmation of the sale by such Person to the Person asserting the claim from which such Losses arise, (y) the prospectus would have corrected such untrue statement or alleged untrue statement or such omission or alleged omission, and (z) the Company has complied with its obligations under Section 5.4(c). Each indemnity and reimbursement of costs and expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party.

(b) Indemnification by Holders. In connection with any Registration Statement in which a holder of Registrable Securities is participating, such holder, or an authorized officer of such holder, shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any Registration Statement or prospectus and agrees, severally and not jointly, to indemnify, to the full extent permitted by law, the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, from and against all Losses arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, prospectus, or form of prospectus, or arising out of or based upon any omission or alleged omission of a material fact required to be

stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue or alleged untrue statement is contained in, or such omission or alleged omission is required to be contained in, any information so furnished in writing by such holder to the Company expressly for use in such Registration Statement or prospectus and that such statement or omission was relied upon by the Company in preparation of such Registration Statement, prospectus or form of prospectus; provided, however, that such holder of Registrable Securities shall not be liable in any such case to the extent that the holder has furnished in writing to the Company within a reasonable period of time prior to the filing of any such Registration Statement or prospectus or amendment or supplement thereto information expressly for use in such Registration Statement or prospectus or any amendment or supplement thereto which corrected or made not misleading, information previously furnished to the Company, and the Company failed to include such information therein. In no event shall the liability of any selling holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds (net of payment of all expenses) received by such holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party.

(c) Conduct of Indemnification Proceedings. If any Person shall be entitled to indemnity hereunder (an “indemnified party”), such indemnified party shall give prompt notice to the party or parties from which such indemnity is sought (the “indemnifying parties”) of the commencement of any action, suit, proceeding or investigation or written threat thereof (a “Proceeding”) with respect to which such indemnified party seeks indemnification or contribution pursuant hereto; provided, however, that the failure to so notify the indemnifying parties shall not relieve the indemnifying parties from any obligation or liability except to the extent that the indemnifying parties have been prejudiced by such failure. The indemnifying parties shall have the right, exercisable by giving written notice to an indemnified party promptly after the receipt of written notice from such indemnified party of such Proceeding, to assume, at the indemnifying parties’ expense, the defense of any such Proceeding, with counsel reasonably satisfactory to such indemnified party; provided, however, that an indemnified party or parties (if more than one such indemnified party is named in any Proceeding) shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless: (i) the indemnifying parties agree to pay such fees and expenses; (ii) the indemnifying parties fail promptly to assume the defense of such Proceeding or fail to employ counsel reasonably satisfactory to such indemnified party or parties; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such indemnified party or parties and the indemnifying parties or an affiliate of the indemnifying parties or such indemnified parties, and there may be one or more defenses available to such indemnified party or parties that are different from or additional to those available to the indemnifying parties, in which case, if such indemnified party or parties notifies the indemnifying parties in writing that it elects to employ separate counsel at the expense of the indemnifying parties, the indemnifying parties shall not have the right to assume the defense thereof and such counsel shall be at the expense of the indemnifying parties, it being understood, however, that, unless there exists a conflict among indemnified parties, the indemnifying parties shall not, in connection with any one such Proceeding or separate but substantially similar or related Proceedings in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses

of more than one separate firm of attorneys (together with appropriate local counsel) at any time for such indemnified party or parties. Whether or not such defense is assumed by the indemnifying parties, such indemnifying parties or indemnified party or parties will not be subject to any liability for any settlement made without its or their consent (but such consent will not be unreasonably withheld). The indemnifying parties shall not consent to entry of any judgment or enter into any settlement which (x) provides for other than monetary damages without the consent of the indemnified party or parties (which consent shall not be unreasonably withheld or delayed) or (y) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party or parties of a release, in form and substance satisfactory to the indemnified party or parties, from all liability in respect of such Proceeding for which such indemnified party would be entitled to indemnification hereunder.

(d) Contribution. If the indemnification provided for in this Section 5.7 is unavailable to an indemnified party or is insufficient to hold such indemnified party harmless for any Losses in respect of which this Section 5.7 would otherwise apply by its terms, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall have a joint and several obligation to contribute to the amount paid or payable by such indemnified party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such indemnifying party, on the one hand, and indemnified party, on the other hand, shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been taken by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include any legal or other fees or expenses incurred by such party in connection with any Proceeding, to the extent such party would have been indemnified for such expenses if the indemnification provided for in Section 5.7(a) or 5.7(b) was available to such party. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5.7(d) were determined by pro-rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 5.7(d). Notwithstanding the provisions of this Section 5.7(d), an indemnifying party that is a selling holder of Registrable Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such indemnifying party exceeds the amount of any damages that such indemnifying party has otherwise been required to pay by reasons of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

5.8 Rules 144 and 144A. At all times after the Company effects its first Public Offering, the Company shall file in a timely manner the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated thereunder (or, if the Company is not required to file such reports, it will, upon the request of any holder of Registrable Securities, make publicly available other information so long as such

information is necessary to permit sales under Rule 144A), and will take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and Rule 144A. Upon the request of any holder of Registrable Securities, the Company shall deliver to such holder a written statement as to whether it has complied with such requirements.

5.9 Underwritten Registrations. No holder of Registrable Securities may participate in any underwritten registration hereunder unless such holder (a) agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

5.10 No Inconsistent Agreements. The Company has not and will not, enter into any agreement with respect to the Company’s securities that is inconsistent with the rights granted to the holders of Registrable Securities in this Article V or otherwise conflicts with the provisions hereof.

(a) Each of VCP, any Co-Investor or any Affiliates thereof that directly or indirectly has an interest in the Company, in each case that is intended to qualify as a “venture capital operating company” as defined in the Plan Asset Regulations (each, a “VCOC Securityholder”), for so long as the VCOC Securityholder, directly or through one or more conduit Subsidiaries, continues to hold any Units (or other securities of the Company into which such Units may be converted or for which such Units may be exchanged), without limitation or prejudice of any the rights provided to the Securityholders hereunder, the Company shall, with respect to each such VCOC Securityholder:

(i) Provide each VCOC Securityholder or its designated representative with:

(ii) Make appropriate directors and officers of the Company, and its subsidiaries, available periodically and at such times as reasonably requested by the VCOC Securityholder for consultation with the VCOC Securityholder or its designated representative with respect to matters relating to the business and affairs of the Company and its Subsidiaries, including significant changes in management personnel and compensation of employees, introduction of new products or new lines of business, important acquisitions or dispositions of plants and equipment, significant research and development programs, the purchasing or selling of important trademarks, licenses or concessions or the proposed commencement or compromise of significant litigation;

(iii) To the extent consistent with applicable law (and with respect to events which require public disclosure, only following the Company’s public disclosure thereof through applicable securities law filings or otherwise), inform the VCOC Securityholder or its designated representative in advance with respect to any significant corporate actions, including extraordinary dividends, mergers, acquisitions or dispositions of assets, issuances of significant amounts of debt or equity and material amendments to the organizational documents of the Company, and to provide the VCOC Securityholder or its designated representative with the right to consult with the Company with respect to such actions; and

(iv) Provide the VCOC Securityholder or its designated representative with such other rights of consultation which the VCOC Securityholder’s counsel may determine to be reasonably necessary under applicable legal authorities promulgated after the date hereof to qualify its investment in the Company as a “venture capital investment” for purposes of the Plan Assets Regulation.

(b) The Company agrees to consider, in good faith, the recommendations of each VCOC Securityholder or its designated representative in connection with the matters on which it is consulted as described above, recognizing that the ultimate discretion with respect to all such matters shall be retained by the Company.

Section 2510.3-101(c)(1) of the Plan Asset Regulations), then the Company and each Securityholder will cooperate in good faith to take all reasonable action necessary to provide that the investment (or at least 51% of the investment valued at cost) of each VCOC Securityholder shall continue to qualify as a “venture capital investment” (as defined in the Plan Asset Regulations).

ARTICLE VII

AMENDMENT AND TERMINATION

7.1 Amendment and Waiver. Except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective against the Company or the Securityholders unless such modification, amendment or waiver is approved in writing by each of the Company and the Vestar Majority Holders; provided that no such modification, amendment or waiver may change the rights or obligations hereunder of (a) holders of Employee Securities in a manner that is material and disproportionately adverse to such holders generally vis-á-vis other holders of Securities unless approved in writing by the Employee Majority Holders or (b) holders of Co-Investor Securities in a manner that is material and disproportionately adverse to such holders generally vis-á-vis other holders of Securities unless approved in writing by the Co-Investor Majority Holders; and provided further, that this Agreement may not be amended so as to discriminate among holders of the same class or series of Securities. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

7.2 Termination of Agreement. This Agreement will terminate in respect of all Securityholders (a) with the written consent of each of the Company, the Vestar Majority Holders, the Co-Investor Majority Holders and the Employee Majority Holders, (b) upon the dissolution, liquidation or winding-up of the Company or (c) upon the consummation of a Sale of the Company (except with respect to the rights to Incidental Registration under Article V, which shall survive). The termination of this Agreement will not affect any indemnification or contribution obligations under Section 5.7, which shall survive such termination.

7.3 Termination as to a Party. Any Person who ceases to hold any Securities shall cease to be a Securityholder and shall have no further rights or obligations under this Agreement (except with respect to any indemnification and contribution obligations under Section 5.7, which shall survive).

7.4 Issuer of Registrable Securities. Prior to distributing to the holders of Units all or substantially all of the securities of any direct or indirect Subsidiary of the Company, the Company shall cause such Subsidiary to execute and deliver a Stockholders Agreement complying with this Section 7.4 (the “Stockholders Agreement”), and each Person, other than the Company, that is a party to this Agreement shall execute and deliver the Stockholders Agreement. The Stockholders Agreement shall be substantially identical to this Agreement, including the provisions that are applicable to an issuer of Registrable Securities hereunder, except that it shall be revised so that such issuer replaces the Company hereunder with respect to provisions that are applicable to the Company hereunder, and such other revisions shall be made

as are necessary or desirable to reflect the fact that the issuer is a corporation rather than a limited liability company. In addition, if the issuer has consummated its initial Public Offering, then any provision of this Agreement that, pursuant to the terms of this Agreement, terminates upon a initial Public Offering shall be excluded from the Stockholders Agreement, and, in any event, this Section 7.4 shall not be included in the Stockholders Agreement.

ARTICLE VIII

PARTICIPATION RIGHTS

8.1 Participation Right. The Company hereby grants to each Employee and Co-Investor who owns Preferred Units or Class A Units the right to irrevocably subscribe for (the “Participation Right”) a pro rata portion of New Units (as defined in Section 8.2 hereof) which the Company, from time to time, proposes to sell or issue in one transaction or a series of related transactions to Vestar or any Affiliate thereof (but not including any employee, director or consultant of the Company or any of its subsidiaries solely in his capacity as such) (collectively, “Vestar Holders”). The pro rata portion of an Employee or Co-Investor for purposes of this Section 8.1 is the ratio of the number of outstanding Preferred Units and Class A Units (to the extent such units are vested (or may become vested as a result of such Transfer) pursuant to the terms and conditions set forth in the applicable Management Unit Subscription Agreement) such Employee or Co-Investor then owns to the total number of Preferred Units and Class A Units then outstanding.

8.2 Definition of New Units. “New Units” shall mean any (i) units of the Company, or (ii) any warrants, rights, calls, options or other securities exchangeable for or exercisable or convertible into units or any other security entitled to participate in the Company’s profits, in each case to be issued by the Company to a Vestar Holder.

8.3 Notice from the Company. If the Company proposes to undertake an issuance of New Units to a Vestar Holder, the Company shall give each Employee and Co-Investor who has a Participation Right under this Article VIII written notice of such proposal (the “Sale Participation Notice”), describing the type of New Units and the price and the terms and conditions upon which the Company proposes to issue the same and setting forth such Securityholder’s pro rata portion of the New Units. For a period of ten (10) business days following the receipt of such notice from the Company the Company shall be deemed to have irrevocably offered to sell to each Employee and Co-Investor such number of New Units as set forth above for the price and upon the terms specified in the notice. Each Employee and Co-Investor may irrevocably exercise the Participation Rights hereunder by giving written notice to the Company and stating therein the quantity of New Units set forth in the Sale Participation Notice to be purchased.

8.4 Sale by the Company. If any Employee or Co-Investor who has a Participation Right under this Article VIII fails to exercise in full such Securityholder’s Participation Right within said ten (10) business day period, the Company shall have one hundred eighty (180) days thereafter to sell the New Units with respect to which the Participation Right was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice given pursuant to Section 8.3.

8.5 Closing. The closing for any such issuance or sale to an Employee or Co-Investor shall take place as proposed by the Company with respect to the New Units to be issued or sold no earlier than ten (10) days after the Company receives notice of the exercise of the Participation Right but no later than sixty (60) days after the issuance of the New Units with respect to which such Participation Right was exercised, at which closing the Company shall deliver certificates for the New Units (if the Units are evidenced by certificates) in the respective names of the purchasing Employee or Co-Investor against receipt of the consideration therefor. If the consideration for the New Units is other than cash, the Employee or Co-Investor shall be entitled to deliver cash in lieu thereof in an amount equal to the fair market value of such non-cash consideration.

8.6 Purchases by Vestar Holder(s). Nothing in this Article VIII shall be deemed to prevent any Vestar Holder from purchasing any New Units without the Company first complying with the provisions of this Article VIII; provided that in connection with such purchase (a) the Company gives prompt notice of such purchase to each Person with a Participation Right, which notice shall describe in reasonable detail the New Units being purchased by the Vestar Holder(s) and the purchase price thereof, and (b) the Vestar Holder(s) and the Company take all steps reasonably necessary to enable each Person with a Participation Right as of such date to effectively exercise his Participation Right with respect to the purchase of a pro rata share of the New Units issued to the Vestar Holder(s) after such purchase by the Vestar Holder(s) on the terms specified in this Article VIII.

8.7 Termination of this Article Upon a Public Offering. The provisions of this Article VIII shall terminate immediately prior to the consummation of a Public Offering.
